7 alternatives to Mailchimp
Compare free and open-source solutions before building your own. Check each option’s license, setup, and limitations.
The heavyweight open-source replacement for segmentation and automation; it also replaces ease with operations.
LicenseGPL-3.0+
PlatformsOn your server
InstallationDownload the production package or install with Composer, then configure PHP, a database, cron, and a mail transport
DataContacts, segments, campaigns, events, and reports live in the configured MySQL or MariaDB database; assets, configuration, logs, and queue files live on the server filesystem.
Limitations compared to MailchimpMautic offers more control but gives up Mailchimp's managed deliverability, upgrades, templates, integrations, and low-maintenance operation.
SetupThe first wall is not the installer but production operation: PHP and database tuning, several cron jobs, HTTPS, backups, upgrades, SMTP/API sending, and DNS authentication.

Campaigns, transactional mail and workflows together; audience CRM depth is thinner.
LicenseAGPL-3.0
PlatformsOn your machine or in the cloud
InstallationHosted signup, or the official Docker Compose stack
DataThe self-hosted stack stores core data in PostgreSQL, jobs and cache in Redis, and objects in MinIO; hosted data is kept in Plunk's EU infrastructure.
Limitations compared to MailchimpPlunk's audience CRM, template ecosystem, campaign analytics, and non-technical marketing workflow are noticeably thinner than Mailchimp's.
SetupHosted use still needs domain authentication; self-hosting adds PostgreSQL, Redis, MinIO, Nginx or another proxy, exposed web and SMTP services, DNS, and ongoing deliverability work.

A modern visual campaign and automation stack; you own the database and the deliverability chores.

PlatformsOn your machine or in the cloud
InstallationHosted signup, or one application container plus PostgreSQL for self-hosting
DataSelf-hosted contacts, campaigns, automations, and events live in PostgreSQL; files can use S3-compatible storage, and the configured email provider receives message payloads. Hosted data lives in Notifuse's cloud.
Limitations compared to MailchimpNotifuse has a smaller template and integration ecosystem, and self-hosters assume database, upgrade, deliverability, and sending-provider work that Mailchimp handles.
SetupSelf-hosting still needs Docker, PostgreSQL, a public HTTPS endpoint, an SMTP or API sending provider, and correctly authenticated sending domains.

Campaigns, forms and automation with many contacts but only 300 daily sends.

PlatformsIn the provider’s cloud
InstallationHosted signup, sender verification, and optional domain authentication
DataContacts, campaigns, templates, automation events, and reports live in Brevo's cloud; exports are available, but the internal storage format is not disclosed.
Limitations compared to MailchimpBrevo's free 300-email daily ceiling makes a single larger campaign slower than Mailchimp and its free emails carry Brevo branding.
SetupThe first meaningful hurdle is verifying the sender and setting SPF/DKIM records for a sending domain; without that, deliverability will disappoint.

InstallationHosted signup, list import, and sender/domain verification
DataSubscribers, campaigns, forms, automation state, and reports live in EmailOctopus's cloud; CSV import/export is supported, while the internal storage format is not disclosed.
Limitations compared to MailchimpFree-plan reports expire after 30 days and the account is limited to one landing page or form, leaving less history and experimentation than Mailchimp.
SetupA sender address must be verified, and serious sending should use an authenticated domain.

Campaigns, forms, analytics and basic automation inside WordPress; the free list stops at 500.

PlatformsOn your machine or in the cloud
InstallationInstall the WordPress plugin, create a MailPoet account, and enter the free Starter-plan key
DataLists, subscribers, newsletters, forms, and settings live in MailPoet tables inside the site's WordPress database; MailPoet's sending service processes recipient addresses and keeps delivery logs, which its documentation says are erased after three months.
Limitations compared to MailchimpIt works only inside WordPress and the free Starter allowance stops at 500 subscribers and 5,000 emails per month.
SetupIt requires an existing, maintained WordPress site plus a plan key and sender/domain approval; it is not a standalone email app.

DataSubscribers, campaigns, forms, automation state, transactional messages, and analytics live in Sender's cloud; the internal storage format is not disclosed.
Limitations compared to MailchimpSender's one-seat branded free plan has a smaller integration and template ecosystem than Mailchimp, even though its send allowance is generous.
SetupThe first real hurdle is authenticating the sending domain and warming a legitimate list rather than merely creating the account.

Mailchimp FreeThe free plan now stops at 250 contacts and omits automation flows; the mascot is mostly a signup form.

They pay because email is business-critical and deliverability problems are expensive. If those points do not matter to you, the options above could save $240 per year.
